Weber’s syndrome

The syndrome is a combination of ophthalmoplegia and contralateral hemiparesis. This is the case of cerebral embolism in the basilar circulation due to chronic atrial fibrillation. Cerebral emboli most commonly involves the carotid circulation.

Weber’s syndrome is just one of the many ways strokes in the basilar artery circulation may present. Infarction in the pons may present with abducens and facial palsy.

Occlusion of the paramedian branches of the posterior or superior cerebellar arteries causes contralateral hemiparesis of the limb and facial muscles accompanied by ipsilateral oculomotor ophthalmoplegia.

The specific oculomotor deficits may include a dilated, unresponsive pupil, a drooping eyelid, and an eye that deviates downward.
